France fullback Mathieu Debuchy, Netherlands goalkeeper Tim Krul and Ivory Coast midfielder Cheik Tiote have all been included.
But ... Moussa Sissoko, who Alan Pardew signed from Toulouse for £2.1 million ... is missing.
Newcastle play Sydney FC in Dunedin on July 22 and the Phoenix in Wellington on July 26 as part of the four-team Football United Tour also featuring West Ham United.
Whether Debuchy, Krul and Tiote make the trip hinges on how far their countries progress at the World Cup. France (3-0 v Honduras), Netherlands (5-1 v Spain) and Ivory Coast (2-1 v Japan) all made impressive starts to the tournament. The World Cup final is on July 14.
